Nemesia plant named ‘Intraigoldtwo’

ABSTRACT

A new and distinct cultivar of  Nemesia  plant named ‘Intraigoldtwo’, characterized by its upright, outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; and golden yellow-colored flowers with yellow orange-colored centers.

Botanical designation: Nemesia hybrida.

Cultivar denomination: ‘INTRAIGOLDTWO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesiaplant, botanically known as Nemesia hybrida and hereinafter referred toby the name ‘Intraigoldtwo’.

The new Nemesia plant is a product of a planned breeding programconducted by the Inventor in Heidesheim and Gensingen, Germany. Theobjective of the breeding program is to create new compact Nemesiaplants with large attractive flowers.

The new Nemesia plant originated from a cross-pollination made by theInventor in 2007 in Heidesheim, Germany of a proprietary selection ofNemesia hybrida identified as code number N 05 82-1, not patented, asthe female, or seed, parent with a proprietary selection of Nemesiahybrida identified as code number N 04 46-17, not patented, as the male,or pollen, parent. The new Nemesia plant was discovered and selected bythe Inventor as a single flowering plant from within the progeny of thestated cross-pollination in a controlled environment in Heidesheim,Germany during the spring of 2008.

Asexual reproduction of the new Nemesia plant by terminal cuttings in acontrolled environment in Gensingen, Germany since 2008, has shown thatthe unique features of this new Nemesia plant are stable and reproducedtrue to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Nemesia have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environmental conditions such as temperature and lightintensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Intraigoldtwo’. These characteristicsin combination distinguish ‘Intraigoldtwo’ as a new and distinct Nemesiaplant:

-   -   1. Upright, outwardly spreading and mounding plant habit.    -   2. Vigorous growth habit.    -   3. Freely branching habit.    -   4. Freely flowering habit.    -   5. Long flowering period.    -   6. Golden yellow-colored flowers with yellow orange-colored        centers.

Plants of the new Nemesia differ from plants of the female parentselection primarily in the following characteristics:

-   -   1. Plants of the new Nemesia are more freely branching than        plants of the female parent selection.    -   2. Plants of the new Nemesia and the female parent selection        differ in flower color as plants of the female parent selection        have white-colored flowers.

Plants of the new Nemesia differ from plants of the male parentselection primarily in the following characteristics:

-   -   1. Plants of the new Nemesia are more compact than and not as        trailing as plants of the male parent selection.    -   2. Plants of the new Nemesia are more freely branching than        plants of the male parent selection.    -   3. Plants of the new Nemesia and the male parent selection        differ in flower color as plants of the male parent selection        have orange-colored flowers.

Plants of the new Nemesia can be compared to plants of Nemesia hybrida‘Intraigold’, disclosed in U.S. Plant Pat. No. 18,075. In side-by-sidecomparisons conducted in Gensingen, Germany, plants of the new Nemesiadiffered from plants of ‘Intraigold’ in the following characteristics:

-   -   1. Plants of the new Nemesia were more vigorous than plants of        ‘Intraigold’.    -   2. Plants of the new Nemesia were more freely branching than        plants of ‘Intraigold’.    -   3. Plants of the new Nemesia and ‘Intraigold’ differed in flower        color.    -   4. Plants of the new Nemesia were less susceptible to root        pathogens than plants of ‘Intraigold’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following descriptionwere grown under conditions which closely approximate commercialproduction conditions during the spring in 16.5-cm containers in anoutdoor nursery in Bonsall, Calif. During the production of the plants,day temperatures ranged from 14° C. to 21° C., night temperatures rangedfrom 7° C. to 10° C. and light levels ranged from 7,000 to 10,000foot-candles. Plants were pinched three times and were 3.5 months oldwhen the photographs and description were taken. In the followingdescription, color references are made to The Royal HorticulturalSociety Colour Chart, 2007 Edition, except where general terms ofordinary dictionary significance are used.
